APPROVALS

All Viking Z SEVEN SCBA are CBRN certified and NIOSH

approved, meeting the NFPA 1981 Standard, 2007 Edition

and the NFPA 1982 Standard, 2007 Edition (when equipped

with PASS) requirements.

NIOSH/OSHA WARNINGS

The following warnings are given in accordance with accept-

ed safety conventions and/or NIOSH/OSHA requirements,

and apply to the use of breathing apparatus in general.

HEALTH LIMITATIONS: Wearers of the SCBA should be

certified medically fit prior to use. In addition, there are both

physiological and psychological limitations which should be

considered before using SCBA. They include, but are not lim-

ited to:

* Emphysema

* Chronic obstructive pulmonary disease

* Bronchial asthma

* X-ray evidence of pneumonia

* Evidence of reduced pulmonary function

* Coronary artery disease

* Severe or progressive hypertension

* Epilepsy (grand mal or petit mal)

* Pernicious anemia

* Diabetes (insipidus or mellitus)

* Breathing difficulties when wearing an SCBA

* Claustrophobia or anxiety when wearing an SCBA

* Abnormal EKG results from resting or stress tests

* Punctured or ruptured ear drum

WORKING TEMPERATURES: The VIKING SCBA is ap-

proved for respiratory protection during entry into or escape

from oxygen deficient atmospheres, gases, and vapors at

temperatures above -25°F. When used below freezing, care

must be exercised to prevent moisture from entering the de-

mand exhalation valve. The facemask should remain on the

docking hook when not in use. On the AirSwitch model, the

slide should be stored in the up position when not in use. For

the RDV demand valve, the RDV should be stored on the

docking station found on the waistbelt. This includes when

cylinders are being changed.

DURATION OF USE: Although the VIKING has been ap-

proved as either a 30-minute, 45-minute, or 60-minute breath-

ing apparatus, the wearer’s varying work rate, physical condi-

tion and other factors could substantially shorten the actual

usable duration of the unit.

SCBA LIMITATIONS: An SCBA can only protect the wear-

er’s respiratory system. Other protection may be necessary

to avoid contamination through skin absorption. If these types

of materials are suspected, an effective full-body covering of

impermeable material must be worn with the SCBA. A univer-

sal Level A HazMat suit is available for the VIKING SCBA

from HazMat suit manufacturers.

FACIAL HAIR: Facial hair or any other items which may in-

terfere with the facemask-to-face seal, including the nosecup,

or the operation of the exhalation valve, must not be allowed.

These include beards, sideburns, mustaches, bangs, head

coverings, or anything else that may interfere with the correct

seal of the facemask and/or nosecup to the face. See NFPA

1500 and ANSI Z88.2

EYE WEAR: Eye glasses shall not be used when the temple

bars interfere with the proper seal of the facemask to the

face. If a user must wear corrective lenses while wearing the

SCBA, they can be mounted in the facemask using a special

lens mounting kit (AVON-ISI p/n 136003) available from

AVON-ISI or through your local AVON-ISI authorized distribu-

tor.

MANUAL BYPASS: In compliance with NIOSH requirements,

the Viking SCBA has a manually operated bypass which pro-

vides a continuous flow of air to the facemask when required,

independent of normal operation of the regulator. The bypass

is opened by turning the red knob on the AirSwitch 90 de-

grees in the direction shown by the knob arrow. The RDV by-

pass opens by turning towards the user. Use of the bypass

will shorten the duration of the SCBA.

All Viking Z SEVEN SCBA are NIOSH CBRN agent approved,

NIOSH approved and NFPA 1981Standard, 2007 Edition

compliant. The Viking Z SEVEN features a heads-up display

(HUD) that monitors cylinder pressure and an emergency RIC

connector that is used to refill the air of a down fire fighter.

The Viking Z SEVEN model has VAS (Voice Amplification

System) and data logging as standard features. Additional

options of the Z SEVEN model include radio interface, voice

activated communications, integrated PASS, buddy breather

and airline. All Vikings are available with light weight carbon

cylinders in 30, 45 or 60 minute rated durations.

The AVON-ISI Viking Z SEVEN is a self-contained, open-cir-

cuit, compressed-air breathing apparatus, which is approved

by the National Institute of Occupational Safety and Health

(NIOSH) and certified compliant to

NFPA 1981Standard on

Open-Circuit Self-Contained Breathing Apparatus for Fire and

Emergency Service

2007

Edition.

Positive pressure inside

the facemask, both during inhalation and exhalation, ensures

that any leakage due to improper fit or component failure will

be an outward flow of air.

The Viking Z SEVEN SCBA consists of several major compo-

nents described in the following paragraphs.

1.1 FACEMASK

The AVON-ISI full facemask

assembly has a two point pull-

forward Nomex net harness

with an optically-corrected,

double curve high-impact

polycarbonate visor. The vi-

sor’s scratch-resistant coating

conforms to NFPA standards.

The interior of the visor has a

permanent anti-fog coating.

The facemask standard seal

is high-strength butyl blend

and has a patented blended

shape which fits the firefight-

er's helmet without readjust-

ment. A standard black inner-mask nosecup reduces dead-air

space and CO2 buildup. The facemask has CBRN labels af-

fixed at both lower corners of the visor.

An in-mask HUD is mounted to the inner-mask nosecup. The

mask display includes five LEDs: red = ¼ full, yellow = ½ full,

1st green = ¾ full, 2nd green = full, and the last elevated yel-

low = low battery indicator. The HUD indicates remaining cyl-

inder pressure and provides the primary end-of-service time

1.0 DESCRIPTION OF VIKING Z SEVEN SCBA

alarm. The HUD can also provide additional status indicators

depending upon the options ordered.

1.2 AIRSWITCH® REGULATOR

The patented AirSwitch second stage regulator is incorporat-

ed into the facemask and combines the demand and exhala-

tion valves to greatly reduce breathing resistance. This also

allows for a longer duration of cylinder use. A speech dia-

phragm provides excellent clarity and voice reproduction

while incorporating the exhalation valve.

The AirSwitch features a fresh air mode which allows users

to go from cylinder air to outside air by depressing the two

control slide tabs inward and then raising the slide upwards

fully. Push down for cylinder or supplied air. The AirSwitch

should stay open prior to donning and doffing of the VIKING

SCBA. The AirSwitch is made of high performance engi-

neered plastics and incorporates a true manual bypass con-

trol for emergency use.

Down for supplied airUp for ambient air

• This approval applies only when the device is supplied with

respirable breathing air through 6 to 300 feet of hose at air

pressures between 80 to 120 pounds per square inch gauge or

from self contained air supply.

NOTE: Viking CBRN SCBAs are not approved for supplied air

use in confirmed or potential CBRN environments.

• If the supplied air fails, open the cylinder valve, unplug supply air

and proceed to fresh air immediately.

• Use adequate skin protection when worn in gases and vapors

that poison by absorption (example: hydrocyanic-acid gas).

S- SPECIAL OR CRITICAL USER’S INSTRUCTIONS, CONTINUED

1.3 REMOVABLE DEMAND VALVE (RDV)

REGULATOR

The Viking RDV

regulator is a mask

mounted second stage

regulator with a 1/8th

turn positive locking

mechanism, which

secures into the

facemask. The RDV

facemask incorporates

a speech diaphragm

that provides excellent

speech clarity even

under heavy breathing.

The standard HUD is still inside the facemask with the

microphone. Docking the RDV on the facemask also aligns

the electronic connection in one simple step. After removing

the RDV from the facemask, it should be stored in the docking

station on the waistbelt strap to keep free of dirt and debris.

1.4 FIRST STAGE PRESSURE REDUCER

Air leaves the cylinder, pass-

es through a sintered bronze

filter in the handwheel elbow

assembly, and then contin-

ues on through a high pres-

sure flexible hose to the first-

stage pressure reducer

where it is reduced to ap-

proximately 125 psi. The re-

ducer is a simple piston type

that requires no adjustment

and incorporates an automat-

ic, self-seating pressure relief valve to protect the low-pres-

sure components downstream. It is made of high quality alu-

minum, and is securely mounted inside the backframe assem-

bly.

1.5 END-OF-SERVICE INDICATORS

The primary

End-of-Service

indica-

tor is incorporated into the HUD.

The display will flash a single red

LED at 23% to 27% of rated cylin-

der pressure per NIOSH require-

ments. The primary end-of-service

alarm meets NFPA 1981, 2007

Edition requirements.

The secondary

End-of-Service

indicator is a bell mounted in-

side the backframe which is set

to activate at 23-27% of rated

cylinder pressure per NIOSH

and NFPA requirements.

1.6 BACKFRAME AND HARNESS

The backframe and harness assembly utilize ergonomic de-

sign principles to produce a com-

fortable, low profile unit that evenly

distributes the SCBA weight be-

tween the wearer’s hips and shoul-

ders.

The unique double-wall backframe

of the Viking protects major airlines,

the first stage reducer, bell alarm

and digital components. A quick-re-

lease cylinder band fits a wide

range of cylinders with an infinitely

adjustable latch to ensure a tight fit-

ting cylinder.

The harness material is NFPA com-

pliant, custom woven KEVLAR®.

The upper harness has very resilient foam rubber padding for

added comfort and PBI/KEVLAR cover for maximum durabili-

ty and protection. There is an optional backframe plate that

can be ordered (p/n 099038) to reinforce the upper harness

straps for departments that do heavy simulation training of

fire fighter rescue operations. A lower lumbar pad is standard

for added comfort and support.

1.7 CONTROL CONSOLE

The control console and PASS assembly communicate with

each other through a wireless

network. The network uses a dis-

creet frequency that eliminates

noise and resistance to other ra-

dio frequencies. This wireless

network joins the Control Con-

sole and PASS assembly to-

gether, allowing for constant data

to be exchanged. The PASS mo-

tion sensor on the Z SEVEN is in

the Control Console. When mo-

tion is detected, the PASS will re-

set for 25 seconds.

NOTE: Only Duracell MN 1500 or Energizer E91 1.5 volt AA

batteries are to be used with the battery packs. Be

sure to place batteries in the direction as indicated

on the battery compartment in order to prolong bat-

tery and fuse life. Use of other batteries will void the

intrinsic safety approval.

alarm

1.7.1 SERVICING CYLINDER VALVE

After each use, and prior to recharging, the cylinder valve must

be inspected for damage. If a new valve is replacing a valve

that was damaged in use, it will be necessary to hydrotest the

cylinder before installing the new valve.

NOTE: Any maintenance on the valve that requires

disassembly should be conducted by an AVON-ISI

Authorized personnel or an AVON-ISI technician who

is well trained in the hazards of high pressure

equipment. Never attempt to remove the valve from

the cylinder while there is any pressure in the

cylinder. Open the valve completely to be sure it is

empty. If the gauge shows pressure but you think the

cylinder is empty, contact the AVON-ISI factory for

advice by calling 888-474-7233.

NOTE: Prior to revalving a cylinder, you must perform the

following inspection:

• Remove o-ring from sealing threads on cylinder

valve.

• Clean threads to remove any lubricant.

• Inspect the cylinder threads, ensuring the threads

are not distorted or cracked.

• Inspect the valve threads, ensuring the threads are

not distorted or cracked.

• Install new o-ring.

If any threads are distorted or cracked, the parts should

be tagged “Out of Service” and be condemned.

1.8 CYLINDER AND VALVE ASSEMBLY

A range of cylinder types and capacities are available on the

VIKING 2216 psi and 4500 psi models. (Please see the table

in Section 1.10 for specifics.)

The cylinder valve is of aluminum construction with a

permanent teflon coating. The valve outlet is a standard

CGA-346 fitting on 2216 psi cylinders, and a standard CGA-

347 fitting on 4500 psi cylinders. Each valve has a dual-

reading pressure gauge. Valve protection is provided by an

elastomeric bumper. See section 2.3.2 for inspection prior to

use.

The valve can be used with AVON- ISI cylinder assemblies

between 23 cubic feet and 87 cubic feel. The cylinder valve

has a burst disc type safety device to protect the cylinder

from over pressurization.

The cylinders and valve are matched according to pressure.

The maximum pressure on the gauge built into the cylinder

valve should match the pressure rating on the cylinder. A

2216 psi valve will not fit into a 4500 psi cylinder and vice

versa. For easy recognition AVON- ISI has made 4500 psi

handwheels red and a 2216 psi handwheel black. (Exception:

Every Viking Z SEVEN has a RIC fitting attached near the

handwheel that allows a downed fire fighter to have their

cylinder charged from an outside source. NFPA 1981, 2007

Edition requires this fitting on all SCBA’s manufactured for fire

fighters. The RIC fitting is compatible with other

manufacturers and is intended as an emergency refill only.

The RIC fitting will not work as a transfill system between two

SCBA’s. There is a dust cap cover for the fitting to prevent

debris on the fitting. See section 4.7 for detailed working

instructions.

1.10 Mounting SCBA

If you mount the Viking Z Seven in a jump seat or mounting

system of any vehicle, you must ensure that the mounting de-

vice meets NFPA standards and that the mounting device

does not interfere with components such as cylinder, that

could cause damage or cause sudden loss of cylinder pres-

sure.

all Viking ST models will have black handwheels no matter

what the pressure rating of the cylinder.)

The cylinder valve has two sets of male threads - one will

screw into the cylinder and the other is used to attach to the

pneumatics of the SCBA. The latter threads are referred to as

CGA (Compressed Gas Association) threads. It is important to

protect the CGA threads so that the pneumatics will always

screw onto them without doing damage to the handwheel on

the pneumatics.

If any threads are distorted or cracked, the parts should

be tagged “Out of Service” and be condemned.

HANDLING PRECAUTIONS:

NEVER LIFT OR CARRY UNIT BY THE HIGH PRESSURE

HOSES. IF A HIGH PRESSURE HOSE BECOMES KINKED

OR OTHERWISE DAMAGED, IT SHOULD BE REPLACED.

CHECK FOR DAMAGE NEXT TO THE METAL ENDS OF

THE HOSE.

monthly. All other breathing apparatus shall additionally be in-

spected after each use.

NOTE: BLACK KEVLAR CYLINDER BAGS (PART #: 138082, 138091, 138092, 138093) ARE OPTIONAL COSMETIC COVERS THAT MAY BE PURCHASED TO COVER CYLINDERS.

2.0 ROUTINE CHECKS

2.3.3 AirSwitch: Open control slide on AirSwitch by

pressing inward and upward on two protruding tabs

on both sides of control slide. Also make sure the

red bypass knob is in the closed position (i.e. fully

turned clockwise when looking at front of mask). See

paragraph 3.1.9 for connection instructions.

RDV: Push inward on the RDV First Breath Button.

Also, make sure the red bypass knob is in the closed

position.

2.3.4 Ensure high pressure handwheel is tightened com-

pletely prior to opening the cylinder valve. Open the

cylinder valve slowly by turning the cylinder valve

knob counterclockwise to the fully open position.

The console should emit an audible chirp. The bell

should activate and then shut off. There should be

no air flow from the facemask. If air is flowing, check

that the bypass valve is closed.

WARNING

ENSURE THAT ONLY A 2216 PSI CYLINDER IS USED

WITH LOW PRESSURE PNEUMATICS AND A 4500 PSI

CYLINDER IS USED WITH HIGH PRESSURE PNEUMAT-

ICS.

2.3.5 CHECK CYLINDER PRESSURE: The heads-up dis-

play will have four lights "on" when the cylinder is

full. When the cylinder pressure is between 3/4 and

7/8, the top green light will be flashing and the ana-

log pressure gauge readout should read at or above

the 7/8th level. If the top green light is "off" or below

the specified levels, refill the cylinder or replace with

a fully charged cylinder.

2.3.6 AirSwitch: While holding the facemask, push down

on the top of the control slide to close the AirSwitch

and QUICKLY push back to the UP position. There

should be a rush of air when the slide is pushed

down, and the air flow should stop when the slide is

in the UP position.

RDV: RDV can be attached from either left or right

orientation. Dock RDV into facemask by turning the

RDV until the bypass knob is facing either the 1

o'clock or 4 o'clock position depending on user com-

fort. Place RDV into mask and rotate till latch is in

the 12 o'clock position (1/8th turn to lock). Inhale to

active airflow. Attempt to rotate RDV to ensure RDV

is locked.

2.3.7 Open bypass and check for constant air flow. Close

bypass.

2.3.8 BATTERY CHECK: If the batteries are low, the top

yellow LED on the HUD will be "ON". In addition, if

equipped with PASS, the control console will make a

beeping noise every 15 seconds to alert the status of

the PASS battery and the console LED will be red.

See paragraph 8.3 to replace the batteries.

2.3.9 LEAK TEST: For the Airswitch, ensure the control

slide is in the up position and the bypass is closed.

For the RDV, push inward on the first breath button

to stop airflow and make sure bypass is closed. Us-

ing a full cylinder, open the cylinder valve slowly until

the pneumatics are completely pressurized. Allow

pressure to stabilize for 30 seconds. Close cylinder

valve for one minute. Open cylinder valve slowly and

observe the analog gauge needle movement. If the

needle on the gauge moves more than 1/8th inch, the

Viking should be removed from service and tagged

for repair.

TECHNICIAN MAINTENANCE

AT LEAST ONCE PER YEAR, THE ENTIRE SCBA SHOULD

BE PLACED OUT OF SERVICE AND TAGGED FOR ANNU-

AL FLOW TESTING BY AN AVON-ISI AUTHORIZED

TRAINED TECHNICIAN.

2.4 SCBA RETIREMENT

Over the course of time, the Viking SCBA needs to be evalu-

ated on its' overall condition. Inspect the Viking's harness as-

sembly for frayed, deteriorating harness', stress cracks in the

backframe and in general, it's overall condition. Another con-

sideration is passing the annual dynamic flow testing require-

ments. Over time components may need to be replaced or

consideration must be made to retire the SCBA.

Fire Department that plans on retiring their SCBA's or no

longer meet the current NFPA requirements, should review

NFPA 1852, 2002 Edition, section 4.3 and 4.6 for guidelines

on retiring an SCBA.

3.1 DONNING PROCEDURES

3.1.1 Position the VIKING SCBA on the ground with the

cylinder valve facing away from the wearer.

3.1.2 Spread the shoulder straps and fold open the side

arms. Ensure all strap assemblies (side and waist)

are fully extended and waist belt buckle assembly is

not connected. Reach inside the harness assembly

and grasp the frame with both hands.

3.1.3 Swing the unit up and over the head, making sure

that the elbows extend through the loops formed by

the shoulder straps. Allow the unit to slide down the

back.

3.1.4 Pull directly down on the shoulder straps to adjust

position of unit on back, attach chest strap.

3.1.5 Connect the waistbelt buckle and adjust waistbelt to

a comfortable snug fit by pulling simultaneously on

both left and right adjustment straps. Tuck the ex-

cess waistbelt and shoulder strap pull-downs inside

the waistbelt.

2.3.10 PASS: If equipped, open cylinder to pressurize the

pneumatics console and PASS alarm should chirp

twice to indicate both devices are active. Allow

PASS to go into pre-alarm and full alarm. Reset

PASS. Inspect console for cracks and abrasion, ob-

serve low battery indicators on front cover of con-

sole. Inspect front speaker cover for cracks. Refer to

section 9.0 for console function buttons. If any part

of console is damaged, tag the unit our of service.

2.3.11 LOW PRESSURE ALARM TEST: Gradually reduce

the system pressure by slightly opening the bypass

valve. Verify that the bell sounds and the mask dis-

play blinks a single red LED as the needle from the

analog gauge is at the 1/4th increment.

2.3.12 Check the RIC fitting to ensure the dust cover is in

place.

ING DONNING PROCEDURES, SECTION 3.

3.0 DONNING PROCEDURES AND SAFETY CHECKS

3.1.8 To connect the facemask to the Viking unit, connect

electronics plug partially into socket, then connect

facemask plug into connector. Press firmly in to lock

both fittings into each socket. A click should be

heard when it is locked in place securely.

NOTE: When connecting the facemask hose to the connec-

tor, make sure both hoses are connected and the

socket sleeve has moved forward. If socket sleeve

has moved forward without the facemask hose con-

nected, air will leak out of the socket connector.

For the RDV mask, the HUD electronic connection

is made when the RDV is docked into the facemask.

Prior to donning the RDV, ensure that the contact

pins are free of any debris.

NOTE: In an IDLH atmosphere, such as a CBRN response,

ensure that the facemask is connected to the pneu-

matic connection prior to entering the hazardous

area to prevent contamination.

NOTE: Prior to docking the RDV, the user can perform a

negative pressure check on the AVON-ISI mask.

Place your hand to block off the RDV opening in the

facemask. Inhale slightly and hold your breath.

Facemask should move inward slightly and stay in

that position unit user exhales. It may be difficult to

perform this with a gloved hand. Annual fit testing is

required to ensure proper fit. Two LED on console

will be green

NOTE: It is not necessary to perform a negative pressure

check on the AirSwitch because it is designed as a

positive pressure facemask. AVON-ISI recommends

annual fit testing to ensure a proper fitting facemask.

AVON-ISI offers facemasks in three different sizes to

ensure a proper fit. Refer to the AVON-ISI Instruction

Sheet for the Viking Facemask (p/n 084022, a/w

A49022) for proper sizing of the facemask.

der valve open, push down on the control slide to ac-

tivate air supply and breathe normally.

RDV positive pressure fit check: With the mask

donned and the RDV docked, inhale to activate air-

flow.

Insert two fingers between the facemask and face.

Gently lift the facemask seal away from the face and

ensure a good outward flow of air, showing that the

facemask pressure is positive. Reseal facemask and

stop breathing for 3 seconds. There should be no

sound of air leaking from the regulator, and there

should be no airflow sensed in the eye region of the

mask.

3.2.2 ALARM CHECK: Close the cylinder valve and con-

tinue to breathe normally. As the air reaches the ¼

full level the red LED light should flash rapidly and

all other lights should be out. The secondary bell

alarm should also activate.

3.2.3 Open cylinder valve. Take two to three deep breaths

to ensure you are getting adequate air into the

facemask. The facemask should not move towards

your face.

3.2.4 AIRSWITCH BYPASS CHECK: The red bypass

knob is located in the center of the AirSwitch. Turn

the bypass knob clockwise as viewed inside the

mask (the direction shown by the knob arrow) to

open the bypass valve. A constant flow of air should

pass into the facemask. Turn the knob in the oppo-

site direction to turn the bypass valve off.

RDV BYPASS CHECK: The bypass knob on the

RDV is located on the right side (from the wearer

view). To open, rotate knob towards the user fully. A

IMPORTANT

THE USER SHOULD BE TRAINED ON HOW TO HANDLE A

POSSIBLE EMERGENCY BEFORE ENTERING A HAZARD-

OUS AREA.

The Viking Z Seven SCBA can be equipped with a variety of

fully-integrated solid state features that offer safety and

communication advantages for the user. Review section 9 for

detailed instructions of available options.

4.1 READING THE HEADS-UP DISPLAY (HUD)

4.1.1 The HUD includes five LED lights: two green, two

yellow and one red. Each of the 4 LEDs in a row

represents a quarter increment of the rated service

pressure. As cylinder pressure decreases, the LEDs

change status. At full rated service pressure, all four

LEDs are on. As cylinder pressure drops below full,

the top green LED begins blinking. At ¾ rated service

pressure, the top green LED turns off and the next

green LED begins blinking. At ½ rated service

pressure, the second green LED turns off and the

yellow LED begins blinking. At ¼ rated service

pressure, the yellow LED turns off, and the red LED

blinks at a fast rate. The top offset yellow light is a low

battery indicator. Refer to the following table for more

information regarding mask pressure display interpre-

tation.

3.2.5 RECHECK CYLINDER PRESSURE: Check the

heads-up display. Four lights should be "on". The

top green light may be flashing, indicating at least

7/8th full. Verify the analog gauge is at or above the

7/8th level.

3.2.6 BATTERY CHECK: The top yellow LED will be "ON"

when the control console batteries are low. If the

pass batteries are low, displays red LED on console

and the pass alarm will chirp every 15 seconds. The

LED on the console will be red. If the SCBA shows a

low battery warning, replace batteries in accordance

with section 8.3.

3.2.7 VAS CHECK

3.2.7.1 Turn SCBA on by either opening cylinder valve or by

manually depressing on buttons.

3.2.7.2 Hold mask up to face and speak into mask.

3.2.7.3 Listen to speech emanating from VAS speaker and

ensure its intelligibility and function.

monitored with the analog pressure gauge. Refer to

chart in paragraph 4.1.1 for the LED light sequence.

4.2.2 The

end-of-service-time

alarms (mask display and

bell) activate when there is approximately 25% of the

full air supply remaining. Egress when alarms

activate. WARNING: 25% OF A FULL CYLINDER

MAY BE INSUFFICIENT IN SOME CIRCUM-

STANCES TO SAFELY EXIT FROM AN IDLH

ATMOSPHERE. One example would be a long-

distance ingress through a continuous IDLH atmo-

sphere. In such situations, begin egress prior to

activation of the

end-of-service-time

indicator.

4.3 CBRN SPECIFIC ACTIONS

Hazardous materials, such as CBRN agents, may

not present immediate effects from exposure, but can

result in delayed impairment, illness, or death.

Use the AVON-ISI Viking with CBRN agent approval

in conjunction with personal protective ensembles

that provide appropriate levels of protection against

dermal hazards. Refer to page 2 of this manual,

Cautions and Limitations for CBRN Protection

C. Harness failure

D. Chattering or unusual noises from SCBA

E. Submersion in water (Note: In this situation the VIKING

will continue to supply air on demand to a depth of at

least 3 meters.)

F. SCBA subjected to high impact such as a fall

G. Air flow decreases such that the facemask moves

inward toward the face during inhalation (Note: In this

situation, open bypass to provide extra, constant flow.)

H. Air flows constantly at a high rate (Note: In this

situation, adjust the flow rate by slowly closing the

cylinder valve until a comfortable flow rate is estab-

lished. The flow rate should match the bypass flow rate

during normal operation.)

I . Digital pressure gauge, mask pressure display, or

other digital options cease to function properly.

4.7 RIC FITTING PROCEDURES

The RIC fitting is designed as an emergency refill only and

has specific uses and functions per NFPA 1981, 2007

Edition. The system can only be used to fill approved SCBA

cylinders. The RIC fitting has an internal balanced piston

that prevents over pressurization of a cylinder. A check valve

prevents fire fighters from transfilling SCBA’s, or any other

unapproved use on AVON-ISI products. Users will be able to

have a 4500 psi cylinder as a supplied air system and

connect to a 2216 psi SCBA RIC connector. Air will stop

flowing automatically from the high-pressure cylinder when

the correct pressure (2216 or 4500) is achieved.

To recharge a cylinder on a downed fire fighter, an approved

charging hose must be used. The AVON-ISI Rescuer uses

the following approved hoses: a 3 foot RIC Charging Hose

(p/n 162051), a 6 foot RIC Charging Hose (p/n 162052), or a

10 foot RIC Charging Hose (p/n 162053) for filling the

cylinder in IDLH atmospheres.

4.7.1 Open cylinder valve of supplied air and remove the

dust cap from the RIC charging hose. Inspect the

fire fighters cylinder for damage and ensure that the

cylinder valve is fully opened.

WARNING

CYLINDERS THAT ARE DAMAGED MAY SUDDENLY

RUPTURE IF CHARGED.

4.7.2 Remove dust cap from the RIC fitting on the SCBA

and attach the RIC charging hose to it. Listen for

leaks on the SCBA that is being filled. Recharging

will take between 2-4 minutes, depending on the

cylinder duration and pressure. When the pressures

equalize, unplug the charging hose from the SCBA

and replace dust covers and exit. During a

prolonged rescue, users can leave the supplied air

cylinder plugged into the downed fire fighter’s

SCBA, adding additional duration to the cylinder.

NOTE: If any time during charging, a leak is detected;

discontinue charging and exit IDLH atmosphere

immediately.

NOTE: In a non-emergency situation, cylinders shall not be

refilled through the RIC.

4.7.3 Once clear of an IDLH atmosphere, close the cylinder

valve on the RIC charging hose. Ensure there is no

debris in the dust cap prior to pushing on the dust

cap. The bottom of the dust cap reads "press to

relieve". With dust cap in place, push down on dust

cap on a hard surface to bleed pressure.

4.7.4 Top off cylinder attached to charging hose before next

use to ensure proper service time.

IMPORTANT

DO NOT REMOVE ANY EQUIPMENT UNTIL YOU ARE

CLEAR OF AN IDLH ATMOSPHERE.

4.8 PASS

The wireless network between the PASS and control console

must always be updating. You must verify on start-up that the

console's LEDs are green. If console LED flashes red for more

than 30 seconds, the PASS will go into alarm and will not turn

off until backframe batteries are removed. Usually the cause is

low battery from either power source that never was changed.

solid red.

BATTERIES FOR PASS: The PASS battery pack

within the backframe powers only the PASS option.

It accommodates two sets of four AA alkaline

batteries. Each set of four is independent of the

other in case of a battery failure. As battery voltage

drops, each set of four batteries switch to the

highest voltage side available until the HUD low

battery indicator shows that all eight batteries need

replacing. The low battery indicator is the in-mask

HUD offset top yellow light, displaying a solid yellow

light. The PASS alarm will also emit an audible chirp

NOTE: The Viking SCBA facemask and elastomers should

every 12 seconds and the console LED pass light will

be red.

NOTE: Electronics will operate at least two hours in low

battery mode.

Battery life depends on many variables. Some fire

departments may use the Viking once every day for

six months before they have to change batteries.

Another fire department may only use the Viking

once a month. Both batteries may have to be

replaced within six months. The difference is the

amount of power loss from using the electronic

options. The Viking Z SEVEN has several options

that can increase battery consumption. The VAS

draws about 700 ma. and radio communications

draws about 250 ma. The rest of the lights that use

LED’s draw very little power. Heat and cold also

affect battery life. During internal heat tests (160 ºF)

and cold tests (-25º F) battery life dropped by 50%.

WARNING

WHEN REPLACING THE AA BATTERIES, ENSURE THAT

THE BATTERIES ARE NOT INSTALLED BACKWARDS

WITHIN THE BATTERY PACK. REVERSING THE

POLARITY OF THE BATTERY FOR EVEN ONE SECOND

CAN CAUSE THE BATTERY TO LEAK OVER TIME. IF A

BATTERY IS INSTALLED BACKWARDS, DO NOT USE

THIS BATTERY BUT DISPOSE OF THIS BATTERY.

FAILURE TO REPLACE THIS BATTERY WILL CAUSE

CORROSION OVER TIME AND CAUSE A COMPLETE

BATTERY FAILURE.

Note: Only Duracell MN 1500 or Energizer E91 AA

batteries are approved for use through intrinsic

safety standards for use on the Viking SCBA.

Chart for Control Console Keys and Description

9.1 CONTROL CONSOLE KEYS & FUNCTIONS

9.1.1 The control console is mounted on the upper left

shoulder strap. As with the HUD, the console turns

on automatically when the cylinder valve is opened.

The control console has several function buttons.

Please review the following diagram for locations

and the chart for function. All locations are from

the users perspective.

9.0 VIKING Z SEVEN OPTIONS

NOTE: At <120 psi = HUD will not display any lights

Auto off delay - after cylinder is closed,

console will turn off automatically after 2

minutes on non-pass units.

(not pictured)

9.1.2 COMMUNICATIONS

The Viking Z SEVEN is available with several communication

options. The microphone is a standard feature and is mounted

inside the facemask on the nosecup. It offers excellent speech

clarity. All communications have a noise suppressor to reduce

exhaled breathing air noise.

Note: The Viking Z SEVEN electronics and pneumatics

turn on automatically when the cylinder valve is

opened. The SCBA electronics can be turned on

manually by depressing the lower two ON/OFF but-

tons on the console.

9.1.2.1 VOICE AMPLIFICATION SYSTEM (VAS)

The VAS uses a sealed, in-mask microphone to

capture the user's voice, amplifies it, and then

broadcasts it from the speaker on the console. This

is particularly useful in communicating with other

people nearby when the SCBA is in the positive

pressure mode. VAS is preset to be voice acti-

vated. You must speak slightly louder than normal

to activate VAS.

The VAS is on standby mode whenever the SCBA

cylinder is opened. When speech is sensed, it turns

on the amplifier and sends it to the console. Shortly

after speech ends, the amplifier goes back into

standby mode.

VAS can be turned off if the user desires. To turn

off the VAS, the cylinder valve must be opened and

power activated to the control console. To disable

the VAS, push inward on the Function key and

push the PTT button. An audible chirp should be

heard. VAS is now in the off setting. To turn VAS

back on, repeat the above function. When the Vi-

king SCBA is powered down, the system will defaut

to VAS "on" when the electronics are activiated.

9.1.2.2 VOICE ACTIVATION LEVELS

The microphone activation level is adjustable for in-

dividual preference. Push the Shift button on the

front of the console inward and hold. The HUD

facemask display will flash the preset point of the

voice activation level. To change the settings, while

holding the Shift key, push the PTT button once.

This will raise the activation point. Continue to push

the PTT to your personal preference. Release the

Shift key to set activation level. To go from Level 4

to Level 1, hold the Shift key inward and push the

PTT button again.

There are ten set points for the voice activation

level. Level 1 is the most sensitive activation point

up to a Level 10 being the least sensitive activation

point. Each level will be displayed a specific num-

ber of HUD light(s) that activate. With each in-

creased level, less inhalation breathing noise is

heard, but voice must be raised higher to begin am-

plification in order for the microphone to detect

speach. The settings are a follows:

Level HUD LED Pattern

1 Flashing Red

2 Red, Flashing Yellow

3 Red, Yellow, Flashing Green

4 Red, Yellow, Green, Flashing Green

5 Red, Yellow, Green, Green

8 Red, Yellow, Flashing Green, Low Bat

9 Red, Yellow, Green, Flashing Green, Low Bat

10 Red, Yellow, Green, Green, Low Bat

1 2 3 4 5 6 7 8 9 10

9.1.2.3 RADIO INTERFACE

When the Z SEVEN is equipped with radio interface, it

has the ability to significantly decrease the background

noise of outgoing transmissions. This is due to the

placement of the sealed microphone inside the

nosecup, which is well insulated from ambient noise. In-

coming transmissions are broadcast from the console

speaker. On units designed for use by law enforcement,

incoming transmissions are recieved through an op-

tional ear speaker.

A separate radio lead is required to integrate the con-

sole to the radio. The radio connects to the interface

cable on the lower control console.

There are two ways to key the radio and transmit: in the

manual mode, press and hold the Push-To-Talk button

(PTT) on the side of the console. As an indication that

the PTT button has been pressed, the right LED indica-

tor light turns green on in the console display and a

solid green light on the HUD. If VAS is installed with

Radio Interface, the VAS is disabled whenever the radio

is keyed.

To activate the hands free VOX mode, press and re-

lease the PTT button twice within one second (double

click). A flashing red light will illuminate on the control

console display. In this mode, the radio is keyed auto-

matically whenever the SCBA senses user speech. The

HUD will illuminate only the top green (full) light when-

ever user speech has keyed the radio. When speech

has ended, the unit automatically turns off the amplifier

to conserve the battery and the HUD again monitors

cylinder pressure. To end the hands free mode, double

click the PTT button again.

9.1.3 Viking Z SEVEN PASS

The PASS on the Viking Z Seven is an NFPA 1982

compliant Personal Alert Safety System (PASS) that

is integrated with the SCBA and with the other

Amount breathing

noise amplified

electronic systems. It requires no adjustments.

The PASS is automatically activated when the

cylinder is opened or may be manually turned on by

pushing both "ON/OFF" side buttons on the console

simultaneously. Once turned on, it normally operates

in the “sensing” mode where it looks for motion at the

console.

9.1.3.1 PASS Operating Instructions

WARNING

ALWAYS TEST THE PASS PRIOR TO ENTRY INTO

A HAZARDOUS ATMOSPHERE. IF THE LOW

BATTERY WARNING SIGNAL ACTIVATES,

INSTALL NEW BATTERIES AFTER USE OR PRIOR

TO USING THE VIKING Z SEVEN. THE CONTROL

CONSOLE WITH PASS SHOULD BE POSITIONED

FLAT AGAINST THE SHOULDER STRAP.

When the PASS is turned on, a chirp will be heard on

the control console speaker, followed by a chirp from

the PASS alarm on the backpack. Additionally, the left

LED users prospective on the console display will

slowly flash green when PASS is on. When there is a

lack of motion sensed at the control console for over

25 seconds, the PASS will go into pre-alarm and

sound an audible warning that will progressively get

louder until the PASS goes into full alarm. While in

pre-alarm, the red (¼ full) and top green (full) lights

on the HUD will flash and the PASS LED light on the

console will change to rapidly flashing red. In pre-

alarm, motion to the control console or pushing the

side buttons on the console will return the PASS to

the sensing mode.

If no motion is sensed for a full 35 seconds (including

the pre-alarm warning), the PASS will go into full

alarm and can only be reset by pushing in on the two

side ON/OFF buttons on the console.

9.1.3.2 PASS Safety Certification and Approval

severely damaged.

9.1.3.4 PASS Limitations

The VIKING Z SEVEN is designed to meet the design

and performance requirements for Personal Alert

Safety Systems (PASS) to be used by firefighters

engaged in rescue, fire fighting, and other hazardous

duties defined in the NFPA 1982 Standard on PASS,

2007 edition. Failure to ensure that the Viking Z

SEVEN PASS is fully operational prior to use may

expose the user to serious injury or death. Although

the Viking Z SEVEN PASS meets the current

standards, there is no guarantee against PASS

failure. Most performance properties of the PASS

cannot be tested by users in the field.

9.1.3.5 PASS Warranty

AVON-ISI warrants the Viking Z SEVEN PASS to be

free from defects in workmanship and materials for a

period of one year from date of purchase. AVON-ISI

will not repair or replace any merchandise that has

been damaged from accident, misuse, or abuse while

in the possession of the end-user. AVON-ISI shall not

be liable for any direct, incidental or other consequen-

tial loss or damage arising out of the failure of the

device to operate. PASS issues may be reported to

AVON-ISI Customer Service at (888) 474-7233. After

working with the manufacturer to resolve any issues,

they may be reported to SEI at (703) 442-5732.

9.2 VIKING STEALTH MODE

The Viking Z-ST model designed for law enforcement has the

capability of turning off the control console. The Stealth Mode

is a standard feature of the Viking Z-ST.

On units with the stealth mode option, depress the funtion

key and the PPT button on the control console for one sec-

ond to turn off VAS. The HUD will still display cylinder pres-

sure and acknowledge radio transmissions. All communica-

tions will be received through the optional ear piece interface

cable. To reset to normal mode, depress the function key and

PTT button on the control console for one second.

LIMITATIONS & OPERATION

NOTE: The EAS option is available on all models of the

Viking SCBA.

9.3.2.1 The EAS tether is designed so you do not have to

unplug the regulator hose from the facemask in an

IDLH atmosphere. The EAS tether includes two feet

of retractable hose stored within the backframe. The

end of the hose includes two couplings, one male and

one female, and a combination handle/dust cap.

When stored, the EAS handle is located on the lower

right side of the backframe (from the user’s perspec-

tive). In an emergency, the EAS tether is pulled out of

the backframe and connected to another EAS tether

forming a four foot long combined tether hose.

9.3.2.2 If the EAS is used, egress immediately to a safe,

respirable atmosphere. The rescuer must monitor

their cylinder air closely due to increased air con-

sumption.

9.3.2.3 Although the EAS is a NIOSH accepted SCBA

accessory, NIOSH does not approve the use of EAS

devices. Use of the EAS voids NIOSH approvals

while in use.

9.3.2.4 REMOVE THE EAS TETHER: Using your right hand,

reach back above the cylinder valve knob and locate

the buddy breather handle. Pull down on the handle

and completely pull out the hose. The tether is

approximately two feet long.

9.3.2.5 CONNECT TO ANOTHER EAS TETHER: Each EAS

tether includes both male and female quick connect

couplings. Connect one coupling, either male or

female, to the opposite coupling on the other EAS
